Reston-based CACI International Inc. has received a $123.4 million contract to continue providing health readiness engineering support for the Navy, Marine Corps and Air Force via the Naval Information Warfare Center (NIWC) Atlantic, the company announced Tuesday.

The South Carolina-based NIWC delivers health information through hardware and software to ensure medical readiness. Under the five year contract, CACI will provide lifecycle support, including engineering and integration, testing, training, cyber security, fleet support, planning, management and reporting for the Theater Medical Information Program and Joint Operational Medicine Information Systems. The Theater Medical Information Program allows electronic health records and other medical information to transmit from the theater of operations via a messaging system, and the Joint Operational Medicine Information System provides technical capabilities to meet existing and emerging operational medicine requirements.

“CACI is the leader in providing enterprise technology for the mission-critical needs of troops across all military services,” CACI CEO and President John Mengucci said in a statement. “For more than 20 years, we have partnered with the Navy to successfully safeguard the health and readiness of our country’s warfighters by modernizing, deploying and sustaining health care records for the fleet, expeditionary forces, airmen and their partners.”
